Two- and three-phase fluid flow in pipelines,
heat transfer, long transmission pipelines
compressible fluids, property profiles,
pressure relief

Whenever the fluid in a pipeline...

...you need a thermophysical property package to determine physical properties of media flowing through the piping.

Whenever there is significant heat transfer between the pipe contents and the ambient (air, water, soil, seawater or any other environment), the heat transfer affects both properties of fluid along the pipe and  the pressure drop. In long transmission pipelines, properties of fluid continually change (especially for compressible fluids) and it affects pressure drop over the pipeline. Simple model assuming constant physical properties cannot be applied in such case. Piping systems also need pressure relief calculations, tanks

For all aforementioned purposes, CHEMCAD or CC-DYNAMICS (and its sub-part CC-SAFETY NET) are the answer. CHEMCAD and CC-DYNAMICS (and CC-SAFETY NET) include:
